We divide our service into synthesis of up to 75 bases (DNA Oligo 5-75 Bases) and synthesis of between 76 and 125 bases (DNA Oligo 76-125 Bases). Standard synthesis is up to 125 bases, however, we are able to synthesis >150 bases, but the outcome is highly dependent on the number of couplings and modifications, please enquire.

The oligonucleotides can be modified with a wide range of modifications both at the 5' end, internally and/or at the 3' end. A list of available modifications can be found here. If you are interested in a modification that is not on the list please don’t hesitate to contact us.

Available synthesis scales:

Oligo 5-75 bases: Oligo 76-125 bases:
40 nmol 40 nmol
200 nmol 200 nmol
1 µmol 1 µmol
2 µmol 2 µmol
These oligos must be HPLC purified if
>50 bases or contains modifications.
These oligos must be HPLC purified.

All oligos are qualified by LC-MS before shipment.
